AssessObligationStatus traverses obligation_id -> (citation_unit) -> accepted
controls -> required evidence -> status (erfuellt|offen|unklar). Evidence
presence is a callback; MVP passes nil (nothing collected yet) -> offen.
citation_spans = "pending" until the Legal-Knowledge-Graph session attaches
them. This is the vertical slice that makes the graph a product feature:
"CRA obligation fulfilled because evidence X/Y/Z is present", not "a doc exists".

Consumes the cross-session contract obligations/obligation_join_keys.json (47
obligation_ids). Interim bridge = citation_unit (our source_norm <-> registry
citation_units), to be hardened to the stable obligation_id (field now optional
on ControlMapping).
ComputeObligationCoverage joins the 47 registry obligations to our accepted
control mappings: covered=2 (user_authentication_required, firmware_software_
authentication), mapped_rejected=3 ((2)(e) -> our OWASP mappings rejected,
route via NIST/BSI), uncovered=42. This coverage signal is the feedback to the
Obligation session for what to cut/refine next.
